http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?answer=13606#post-id-13606You can do `frame=False` and `axes=True`, but doubtless you're talking about something more substantial, and these leave ... less than desirable results. I'm not sure why the axes are in the wrong place sometimes, though I believe there is a ticket open for this.Wed, 23 May 2012 16:25:49 -0500http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?answer=13606#post-id-13606Comment by kcrisman for <p>You can do <code>frame=False</code> and <code>axes=True</code>, but doubtless you're talking about something more substantial, and these leave ... less than desirable results.

http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?comment=19742#post-id-19742That's probably what I would do at this point too. It would be great to have a nice axes option for 3d graphics.Thu, 24 May 2012 06:10:09 -0500http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?comment=19742#post-id-19742Comment by calc314 for <p>You can do <code>frame=False</code> and <code>axes=True</code>, but doubtless you're talking about something more substantial, and these leave ... less than desirable results.

http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?comment=19746#post-id-19746Thanks for the help. I really went a few rounds with the plot3d options this afternoon and ended up using the line command to create some axes. Just wanted to make sure I hadn't missed something in the documentation somehow.Wed, 23 May 2012 17:25:29 -0500http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?comment=19746#post-id-19746Answer by ndomes for <p>Is there a way to set the kind of axes shown in a 3d plot?

You can write your own python function to draw axes, something like:
def axes(xmin=-1,xmax=1,ymin=-1,ymax=1,zmin=-1,zmax=1,**kwds):
ex = vector((1,0,0))
ey = vector((0,1,0))
ez = vector((0,0,1))
G = line3d([xmin*ex,xmax*ex],**kwds)
G += line3d([ymin*ey,ymax*ey],**kwds)
G += line3d([zmin*ez,zmax*ez],**kwds)
return G
axes(xmax=2,zmax=4,color='red',thickness=2).show()Thu, 24 May 2012 22:39:41 -0500http://ask.sagemath.org/question/8997/set-axes-in-3d-plot/?answer=13611#post-id-13611
